Although erase is often used as a synonym for wipe, that term is a little misleading -- it isn't possible to actually erase hard drive data. Deleting a file only removes the file listing, which serves as a shortcut. The data is still on the computer and easily accessible to anyone with the right program and/or know-how.
First developed by Tim Berners-Lee in 1990, HTML is short for HyperText Markup Language. HTML is used to create electronic documents (called pages) that are displayed on the World Wide Web.
When you save an HTML document, you can use either the .html or the .htm file extension. HTML consists of the set of markup symbols or codes inserted in a file intended for display on a World Wide Web browser page. The markup tells the browser how to display a Web page's words and images for the user. HTM and HTML are the most common type of documents used to build static webpages. Both HTM and HTML may contain links to images, audio, video and scripts.
